The iambic trimeter derives its name from its essential shape, which is three metrical units (hence trimeter) which are each basically iambic in form. The iambic metron has the following shape (where the x is an anceps, the - is a longum, and the u is a brevis):
Hence, reversing the current running though a wire will have the affect of reversing the direction of the magnetic force at a point some distance away from the wire. The affect that this has on the overall magnetic field depends on the shape of the wire.
The magnetic field is perpendicular to the axis of the wire.Part AWhat is the strength of the magnetic field?ANSWER:8.00Ã10 â2 CorrectPart BWhat is the direction of the magnetic field?ANSWER: Into the pageOut of the pageCorrect Problem 34.12 The loop in the figure is being pushed into the 0.20 magnetic field at 50.
